Abstract
In the present paper, a flattening contact analysis of CNT-Al nanocomposite is presented for both loading and unloading phases. APDL code is used in ANSYS framework to create the FE model to analyse the contact behaviour between a frictionless cylinder (CNT-Al) and a rigid flat. The developed model has been validated against established results of certain problems with lesser complexity. The contact force, contact area, von Mises stresses and nodal displacements are extracted from the simulated solution. These parameters are noted at the end of the loading step and also once unloading is completed from a certain interference. It has been found that as CNT radius increases, the contact properties get decreased. It's also observed that beyond a certain CNT radius, the contact properties of CNT-Al nanocomposite materials start to resemble those of the matrix material and eventually fall below the matrix material.
